Abstract
The invention relates to a refining method of an aluminum alloy material for heat exchangers. The aluminum alloy material comprises the following components in percentage by weight: manganese, copper, silicon, magnesium, zirconium, iron, titanium, tungsten, and the balance of aluminum inevitable impurities. The components are smelted and cast to obtain the aluminum alloy ingot. Compared with the existing aluminum alloy pipe, the aluminum alloy pipe provided by the invention has greatly higher strength, higher mechanical toughness and greatly improved corrosion resistance.
Description
Technical field
The invention belongs to field of aluminum alloys, specifically refer to a kind of heat exchanger aluminium alloy method for refining.
Background technology
Heat exchanger now mainly adopts standard aluminum alloy pipe, but the existing aluminium alloy pipe using can not meet light-weighted requirement, because in the situation that lightization quantizes, it is thinner that tube wall becomes, but existing aluminum alloy materials is after tube wall attenuation, physical strength reduces, and the resistance to corrosion of thin tubing is not enough to be adapted to heat exchanger field.
In order to improve the performance ，Xian various countries of aluminium alloy, all at the new aluminum alloy materials of exploitation, to adapt to, can manufacture the needs that thinner aluminium alloy pipe meets heat exchanger.In existing disclosed technical scheme, be all to contain optional in manganese, copper, silicon, magnesium or vanadium, chromium, titanium, and in some disclosed technology, require to contain zirconium or require not contain zirconium, or require in aluminum alloy materials, to contain ferro element, to reduce the hot crackability of copper.
But in metal field, the problem of existence is, even identical composition, but the subtle change of technique may will cause the greatest differences of the finished product performance, and this situation has been the common practise of this area.
Summary of the invention
The object of this invention is to provide a kind of raising intensity of aluminum alloy, and improve the aluminium alloy method for refining of corrosion resistance of aluminum alloy.
The present invention is achieved by the following technical solutions:
A kind of heat exchanger aluminium alloy method for refining, its material composition includes by weight percentage, 1.35% manganese, the copper of 0.6-1.2%, the silicon of 0.35-0.45%, the zirconium of the magnesium of 0.3-0.5%, 0.1-0.2%, the titanium of the iron of 0.3-0.6%, 0.1-0.15%, the tungsten of 0.05-0.075%, and surplus is aluminium and inevitable impurity;
First melting partinium adds half aluminium after partinium melts completely, after aluminium melts completely, adds all the other each components and remaining aluminium, carries out melting;
After removing the gred, aluminum alloy melt is put into and bred stove and carry out constant temperature and breed after 30 minutes and cast;
In when casting, adopt that at the uniform velocity constant temperature is cooling, speed of cooling is 5 ℃/sec-35 ℃/sec, while being cooled to 580 ℃-600 ℃, holding temperature is after 0.5-2 hour, 3 ℃/sec-8 ℃/sec at the uniform velocity constant temperature after being cooled to 150 ℃-180 ℃, naturally cool to normal temperature, obtain aluminum alloy ingot.
The weight ratio of described copper and iron is 2:1.
The weight ratio of described titanium and tungsten is 2:1.
When carrying out aluminium alloy smelting, tungsten adds in partinium mode, and in partinium, to account for weight percent be 10% to tungsten.
Zirconium adds in zirconium alloy mode, and wherein, zirconium accounts for 5% of zirconium alloy weight percent.
The aluminium alloy pipe that co-occurrence of the present invention is used is compared, and not only aspect intensity, is greatly improved, but also has improved mechanical tenacity, and have greatly improved aspect corrosion resistance nature.
